HT UG CABLE LAYING - IMPORTANT DATA

Clearance from other cables :-

1. Power cable to Power cable             -      Clearance is not necessary. However, larger 
                                                                       clearance  better would be current carrying capacity.

2. Power cable to control cable                           -      0.2 metre

3. Power cable to communication  cable            -      0.3 metre

4. Power cable to Gas / Water main                   -      0.3 metre

5. Power cable should not be laid above the telecom cable.

6. Size of the protection pipe (G.I) for the UG cable should be at least 1.5 times the outer dia. of
    the cable.
